Arctic Sun Starting To Fade

Over the next six weeks, the amount of solar energy being received in the Arctic will drop to very low levels.

    Real world evidence of the thermal lag in the ocean atmosphere weather patterns. Low ice should be about 2 months from now! The pot of water on a stove and removed when it starts boiling comes to mind.

    But all those excess CO2 molecules will just keep reradiating and melt the ice, even in the dark. CO2 is the Devil!

      Actually, does anyone now what the supposed time constant is for something like that? I assume that radiative heat transfer is kinetically labile.

      • How long does it take to cool down after the sun sets?

      • Grumpy Grampy ;) says:

        Til sunrise the next day! Or in this case until the sun rises over the horizon in the arctic region.

        Exactly, that’s what I was thinking. Though in the Arctic, there is much less water vapor, so the air will cool down more quickly (disregarding things like the lower absolute temperature radiating to space less than warming temps). I would think that the heat transfer in the ocean to the ocean surface is much more dominating than anything else within just a few days after “sunset”, as all of the original “trapped” heat would have dissipated.

        Ice has more of an insulating effect than water vapor and snow even more than ice. To stay warm in a blizzard you dig a shelter in the snow.
